    NP205 question (pics included)

    I have mounted several sets of 285s with my $40 harbor freight tire "machine", which is basically a mount that holds the tire and wheel at waist height . The tall sidewall actually makes them pretty easy to install.

    What have you done to your square lately??

    Swapped in a new fuel tank valve to replace the one I just installed new in September. At least napa warranteed it. Once again, I hope all engineers are cursed to spend eternity working on the things they designed. My particular complaint is to whoever designed the mounting bolts for the fuel...

    Engine starts and goes to full RPM???

    Is it drive by wire, or does it still have a cable activated throttle? If cable type, is the throttle linkage stuck open?

    Can't believe this gas mileage

    Hope is a good thing, but I would be surprised at those numbers. Never trust the gauge. You need to fill the tank, drive for a while, top the tank back off, then divide the miles traveled by gallons used.

    Opinions

    The 465 is pretty bulletproof , so as long as it's working fine now, I would just run it as is. New clutch components when reassembling, of course.

    Aftermarket dash cluster

    I made my own. I used Sunpro mechanical gauges and an eBay tach (which is malfunctioning, so time to find a quality one, which is tough in 2 1\8" ). Still used the factory Speedo and fuel gauge.

    lowering / easier entry for 84 C-20

    It looks like the tire you are looking at is 2" shorter, so it will drop you by 1" , not two. You can pull the front tire, then lower the jack in one inch increments, until you find a height you are comfortable with, then go from there.

    Replacement tail light sockets

    On the screws, if you are about the thin pieces that go over the sheet metal tabs to thread sheet metal s rees into, they are called u nuts. Any decent hardware store should sell them, organic harbor freight has a kit for around $7, I think.

    15's or 20's

    I agree with Craig that they look like a 275. I have them on my F1. And I prefer 15s to rubber band 20s. Personal preference.

    "The Highway Hauler"

    A 4x4 with a 4 speed sm465 at 75 will be screaming without an overdrive if running any gear\tire combo that would be usable in general 4x4 use, from what I am familiar wjth. Not saying it can't be done, but will be challenging. I'm looking forward to your progress and solutions.

    What is the missing rubber piece called and where can I find them

    https://www.lmctruck.com/1973-87-chevy-gmc/suspension-front-rear/cc-1973-87-rear-suspension-4-wheel-drive looks like #14 is what you need. But lmc shipping sucks.

    '86 C10 temp gauge

    Possibly the printed circuit on the back of the gauge cluster.

    Fuel gauge

    No, it won't work. You have an open circuit, so it's a broken wire, bad sender, etc. If you can get to it, you can pull the sending unit wire and put an ohm meter between the pin on the sender and ground. If it shows between 0-90 ohms, the sender is working and you have a wiring problem. If...

    What have you done to your square lately??

    I proved the old adage of "if you think it's an ignition problem, it's probably a fuel issue , and vice versa" correct. Last week it started cutting out and bucking, and did it on both tanks, so I figured ignition . Ordered a new hei refurb kit from Skip White. Waited a week and installed it...

    1988 C30 Dually Crew Cab Charlotte, NC

    Welcome. The square body was used in crew cabs, suburbans, and blazers until 91, I believe. I'm sure others will correct me otherwise.

    Thx. On my Dodge, I mounted them under the bumper I made. I prefer the recessed look better.

    Is there market for used winches?

    It's only been about 35 years since I had a warm 8274, but I believe the P.O. Had used a round trailer connector for the remote.

    Interior Rear View Mirror

    Eskimomann, how did you get your old mirror mounting tab off? I just picked up that mirror, but am reluctant to pull my tab off my brand new windshield. They just had to make the new tab slightly bigger...
